PUNCHlNG-BAG ATTACHMENT.

SPECIFICATION forming part of Letters Patent N0. 770,869, dated September 27, 1904. Application filed November 16, 1933. Serial No. 181,364. (No model.)

To all whmn it 'nmg concern." Be it known that I, KATHRYN C. Ron, a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a certain new and useful Im provement in Punching-Bag Attachments, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to anchoring devices whereby articles or apparatus to be suspended may be readily connected with or disconnected from their stationary or supporting parts.

My invention more particularly relates to striking-bags, and is of particular service where the bag is suspended by two elastic supporting-cords, which are secured at vertically opposite points to suitable stationary parts, such as the floor and ceiling, an anchoring device of my invention being desirably provided at each anchoring-point. It will be obvious, however, that a permanent upper fastening may be employed in cases where it is not essential to entirely remove the apparatus when the same is not in service, in which instance the lower device may be disconnected to permit the bag and its cords to be festooned or hung to one side of the casing.

My device is especially serviceable in connection with a striking bag adapted to be installed in places of restricted space, such as doorways, and permits the ready removal of the bag, together with its attachments, after usage to free the space. of its encumbrance. To this end I construct each anchoring device in two parts or elements that are united when the device is in service, but, are separable to permit the removal and anchorage of the apparatus for'which the anchoring device is provided. One member or part of the anchoring device is a fastening-plate, that is preferably secured permanently to a suitable stationary part, while the other member or part is in fastening engagement with its associated bagcord. Preferably one end of each of the upper and lower cords is provided with an enlargement, which in the preferred embodiment constitutes one member, preferably the ball, of a ball-and-socket join t, the other member of each ball-and-socket joint, preferably the socket also, forms one of the separable members of the anchoring device.

I will describe my device more particularly with reference to the accompanying drawings, in Which- Figure 1 is a view in elevation showingone adaptation of my device. Fig. 2 is a detail sectional view on line 2 2 of Fig. 1. Fig. 3 is a plan view of the device shown in Fig. 2. Fig. 4 is a similar view to Fig. 2, illustrating a modified form of the device and showing parts thereof in elevation.

Like parts are indicated by similar characters of reference throughout the different views.

My invention is illustrated in connection with a striking-bag 1, suspended between two oppositely-extending cords 2 in the usual manner. A familiar form of bag is shown, one of its supporting-cords 2 being suspended from the upper member of the door-casing, while the other cord 2 is shown anchored at the threshold of the door. Each of the supporting-cords 2 is provided at one end with an enlargement 3, which is preferably semispherical in form and of hollow construction. A suitable aperture in said enlargement or ball 3 is provided through which the cord passes, while the hollow portion of the ball serves to accommodate a suitable stop, such as a knot formed on the end of the cord, to prevent disengagement of the connected parts. Said ball 3 is preferably incased in a cylindric cap 4, a portion of the interior thereof and the ball 3 being of complemental formation. The cap 4 is provided with an aperture inone end through which a portion ofthe ball 3 protrudes to permit of free lateral play to the supporting-cord without bringing the same into contact with the metallic parts. Said enlargement or ball 3 and the cylindric cap 4 form the ball-and-socket connection which forms a part of the anchoring device, and said cap 4 also constitutes one of theseparable members of the anchoring device. -VVhen the parts are in position, the walls of said cap 4 extend away from the ball 3' to provide means whereby the same may be connected with the stationary fastening-plate. Said connecting means, as shown, consist of screwthreads formed on the exterior of the cap 4:, near one end thereof, at 7, to engage similar screw-threads on the fastening-plate 5,where by the parts may be connected or disconnected when the apparatus is installed or detached. Said fastening-plate preferably consists of a flat annular ring provided with a centrallydisposed aperture adapted to receive the cylindrical end of the cap i. Interior screwthreads are formed on the plate 5, which engage the threaded portion 7 of the cap 4. When the anchoring device is frequently eonnected and disconnected, the cap 4 may be turned by hand; but when said parts are used as a permanent anchoring device the application of a wrench may be necessary to disconnect the parts should the threads thereof become set by rust. I therefore desirably provide said cap 4 with suitable gripping-surfaces, to which a wrench or like instrument may be applied. The fastening-plate 5 is of suflicient diameter to accommodate apertures for Wood-screws by means of which said plate is anchored to the floor or other suitable stationary part.

In Fig. 4 is shown a modified form of the anchoring device. In this construction the fastening-plate 6 is shown chamfered from the central aperture outwardly to the periphery thereof. This form of the device is desirably used in places where an obstruction, such as an attachment of this nature, is not objectionable. It is also obvious that this form of the device not only reduces the obstruction offered by the ring, but also presents the advantage of being attachable to any structural surface without the use of special tools.

It is obvious that changes may be made in the embodiments shown without departing from the spirit of the invention, and I do not wish to be limited to the precise construction illustrated; but,

Having described my invention, I claim as new, and desire to secure by Letters Patent, the following:

1. The combination with a cord, of a balland-socket anchoring device therefor the ball portion being carried by the cord and a stationary fastening-plate having threaded en gagement with the socket, substantially as described.

2. The combination with a cord, of a balland-socket anchoring device therefor the ball portion being carried by the cord and a stationary fastening-plate having separable engagement with the socket, substantially as described.

3. The combination with a cord, of a fastening device having two elements, one of said elements being movable and carried by the cord the other element engaging said movable element, and a stationary fasteningplate with which said last-mentioned element has separable engagement, substantially as described.

4. The combination with a cord, of a fastening device having two elements, one of said elements being movable and carried by the cord the other element engaging said movable element, and a stationary fasteningplate with which said last-mentioned element has threaded engagement, substantially as described.

In witness whereof I hereunto subscribe my name this 12th day of November, A. D. 1903.
